The week-long tour opens June 15 at the Spreckels Theatre in San Diego, where Kristofferson will be joined by Mariachi Divas, and continues with stops June 16 in Fresno (Rojas with Trio Ellas), June 16 in Stockton (support act to be arranged), June 19 in Bakersfield (Los Lobos), June 21 in Oxnard (Mariachi Los Camperos de Nati Cano) and June 22 in San Jose (Los Texmaniacs).

“It’s an honor for me to share my talent with an organization such as the UFW and its cause of advancing the lives of thousands of workers that put food on all of our tables,” Kristofferson said in a statement. “Joining forces with renowned Latino performers through these special performances offers fans great music with a great cause.”

Other activities will be part of the UFW’s 50th anniversary convention being held Thursday through Sunday in Bakersfield. Details on the UFW’s website.
